parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride
collision, such as a collision in which the
front of the vehicle underrides, or goes
under, the bed of a truck
Depending on the type of collision, it is
●
possible that only the seat belt preten-
sioners will activate.
●
The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
The SRS seat cushion airbags on the rear
●
seat will not operate if the occupant is not
wearing a seat belt.
■
SRS airbag deployment conditions (SRS
side and curtain shield airbags)
The SRS side and curtain shield airbags
●
will deploy in the event of an impact that
exceeds the set threshold level (the level
of force corresponding to the impact
force produced by an approximately
3300 lb. [1500 kg] vehicle colliding with
the vehicle cabin from a direction per-
pendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).
●
Both SRS curtain shield airbags may
deploy in the event of a severe side colli-
sion.
●
Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.
Both SRS curtain shield airbags may also
●
deploy in the event of a severe frontal col-
lision.
Conditions under which the SRS air-
■
bags may deploy (inflate), other than a
collision
The SRS front airbags, SRS curtain shield
airbags and SRS seat cushion airbags may
also deploy if a serious impact occurs to the
underside of your vehicle. Some examples
are shown in the illustration.
Hitting a curb, edge of pavement or hard
●
surface
LS500_OM_(U)_1810
Falling into or jumping over a deep hole
●
●
Landing hard or falling
The SRS curtain shield airbags may also
deploy under the situations shown in the
illustration.
●
The angle of vehicle tip-up is marginal.
The vehicle skids and hits a curb stone.
●
Types of collisions that may not deploy
■
the SRS airbags (SRS front airbags/SRS
seat cushion airbags)
The SRS front airbags and SRS seat cushion
airbags do not generally inflate if the vehicle
is involved in a side or rear collision, if it rolls
over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any
type causes sufficient forward deceleration
of the vehicle, deployment of the SRS front
airbags and SRS seat cushion airbags may
occur.

Collision from the side

Collision from the rear
